Description

  The present invention relates to a mobile phone suitable for executing a game.

  In recent years, an increasing number of users run games on mobile phones. The game program executed on the mobile phone can be downloaded from a site providing the game, for example, connected to a network, or read through a removable recording medium.

  The mobile phone is provided with a plurality of numeric keys and call keys operated when making a voice call, and function keys for executing various functions. When a game is executed on a mobile phone, a key to be executed in the game is assigned to an existing key. Since many mobile phones are configured so that key operations can be performed with one hand, functions are often assigned to appropriate keys so that they can be operated with one hand even when a game is executed.

In addition, a mobile phone game controller for realizing an operation feeling close to that of a dedicated video game machine when a game is executed by a mobile phone has been considered (see Patent Document 1). The mobile phone game controller described in Patent Document 1 is provided with a direction instruction key, a determination selection key, a call switching key, and the like, and can be used by connecting to the mobile phone body through an external connection terminal. By using the mobile phone game controller directly connected to the mobile phone main body, it becomes possible to operate the keys originally attached to the mobile phone main body from the mobile phone controller. You will be able to play games as if you were using a dedicated game machine for the center.

  A plurality of back keys 38 are provided on the back surface of the main unit 30 as shown in FIG. A predetermined function is assigned to the back key 38 depending on whether the normal telephone function is used or the game is executed. As shown in FIG. 2B, a sub display 39 and a camera unit 40 are provided on the back surface of the display unit 31.

  The sensor 20a detects whether the display unit 31 is in an open state or a closed state by the rotation of the first shaft of the hinge mechanism 33. Further, the sensor 20b is arranged such that the rotation of the second axis of the hinge mechanism 33 causes the display unit 31 to be in a normal use direction (forward direction) (when the key of the main unit 30 is arranged when the display unit 31 is in the open state as shown in FIG. It is detected whether or not the display 36 is facing in the same direction as the provided surface. Further, the sensor 20 c detects whether or not the cross key unit 32 is in a state of being pulled out from the main body unit 30.

FIG. 3 shows a usage pattern of the mobile phone 1 when the game is executed.
FIG. 3A shows a usage pattern suitable for a game in which a key is operated with one hand. The switching control unit 10e indicates that the display unit 31 is in an open state from the sensor 20, the display unit 31 is directed in the forward direction without rotation by the second axis of the hinge mechanism 33, and the cross key unit 32 is further connected to the main unit. If it is notified that it is in the state of being housed in 30, it is determined that it is in the state shown in FIG.

  In the case of a usage pattern suitable for a game in which a key is operated with both hands, first, as shown in FIG. 3B, the display unit 31 is rotated 180 ° from the forward direction by the second axis of the hinge mechanism 33. The Then, the first shaft of the hinge mechanism 33 is brought into a closed state in which the back surface of the display unit 31 and the surface on which the key of the main unit 30 is arranged are overlapped.

As shown in FIG. 4, after the display unit 31 is rotated by the second axis of the hinge mechanism 33, the display 36 provided in the display unit 31 is exposed by overlapping the main body unit 30 by the first axis. It becomes a state. Further, since the length of the display unit 31 in the longitudinal direction is shorter than that of the main unit 30 and the function keys 35 provided on the main unit 30 are arranged near the end, the display unit 31 is connected to the main unit 30. Even in the closed state, the function key 35 can be operated.

  Then, the cross key unit 32 housed in the main unit 30 is pulled out from the main unit 30 as shown in FIG. FIG. 3D shows a state in which the cross key unit 32 is pulled out to a position where the cross key 37 can be operated.

  FIG. 5 shows a configuration in which the cross key unit 32 is accommodated in the main unit 30 so as to be slidable. FIG. 5A is a perspective view showing the configuration of the main body unit 30 and FIG. 5B is a cross key unit 32. As shown in FIG. 5A, a recess for storing the cross key unit 32 is formed on the side where the hinge mechanism 33 of the main unit 30 is provided, and a slide groove is formed on the side surface corresponding to the recess. 42 is formed. On the other hand, on the side surface of the cross key unit 32, as shown in FIG. 5B, a convex engagement portion 43 that engages with the slide groove 42 is formed. As shown in FIG. 5C, the cross key unit 32 is attached to the main unit 30 so that the engaging portion 43 engages with the slide groove 42. Therefore, the cross key unit 32 is accommodated in the main unit 30 so as to be slidable along the slide groove 42 as shown in FIG.

FIG. 6 shows a usage form in which the cellular phone 1 is operated with keys by both hands.
As shown in FIG. 6, the display unit 31 is overlapped with the main body unit 30 and the cross key unit 32 is pulled out from the main body unit 30 and used sideways, whereby the display 36 is placed in the center and the keys on both sides thereof. Can be arranged. Accordingly, it is possible to operate the keys with both hands while holding the mobile phone 1 with both hands in the same manner as a certain type of portable game machine. In the example shown in FIG. 6, a cross key 37 capable of instructing up, down, left and right directions is arranged on the left side of the display 36, and function keys 35 to which various functions are assigned are arranged on the right side. Further, the back key 38 provided on the back surface of the main unit 30 can also be operated in the usage pattern shown in FIG. The usage pattern shown in FIG. 6 is an example, and other key arrangements are possible, for example, the cross key 37 is arranged on the right side of the display 36 and the function key 35 is arranged on the left side.

  6 and FIG. 3A, the arrangement relationship of the keys and the display direction of the image on the display 36 are different. The switching control unit 10e of the control unit 10 detects which usage mode is used, and changes in the functions assigned to the keys and changes in the image display direction on the display 36 will be described below. Execute.

  First, a function switching control process for changing a function assigned to a key used in a game will be described with reference to a flowchart shown in FIG.

  The switching control unit 10e detects that the cross key unit 32 is in the state of being pulled out from the main body unit 30 by the notification from the sensor 20c (step A1, Yes), and further displays the display by the notification from the sensors 20a and 20b. When it is detected that the unit 31 is in a closed state where it is overlapped with the main unit 30 so as to expose the display 36 (step A2, Yes), it is determined that the usage mode is changed to that shown in FIG. .

  In this case, the switching control unit 10e refers to the function switching table 10f and changes the function assigned to each key of the cross key 37 (step A3). Further, the switching control unit 10e refers to the function switching table 10f and changes the function assigned to the function key 35 of the main unit 30 (step A4).

  For example, in the usage mode shown in FIG. 3A, the cross key 37 has an A position key up, a B position key left, a C position key down, and a D position as shown in FIG. 8A. The key is assigned as a key for indicating the right direction. On the other hand, in the usage mode used sideways shown in FIG. 6, as shown in FIG. 89, the A position key is left, the B position key is down, the C position key is right, and the D position is The key will be placed on top. The switching control unit 10e refers to the function switching table 10f and changes the function assigned to each key in order to provide the same operability when executing the game.

  FIG. 9 shows an example of data set in the function switching table 10f. As shown in FIG. 9, for the keys A, B, C, and D of the cross key 37, in the usage mode 1 shown in FIG. In the case of usage mode 2 shown in FIG. 6, the left, lower, right, and upward direction instruction functions are set.

  Accordingly, when the switching control unit 10e detects that the usage mode 1 (FIG. 3A) is changed to the usage mode 2 (FIG. 6), the A, B, C, and D positions of the cross key 37 are detected. Change the function assigned to each key to left, down, right, and up.

  Similarly, the keys other than the cross key 37 provided on the cross key unit 32 and the functions assigned to the function keys 35 provided on the main unit 30 are also set for the usage mode 2 of the function switching table 10f. Change to the function you have. Further, by changing the assigned function for the back key 38 provided on the back surface of the main unit 30, an operation according to the usage pattern can be performed.

  Next, a display switching control process for changing the display direction of the image displayed on the display 36 will be described with reference to the flowchart shown in FIG.

  Similar to the function switching control process, the switching control unit 10e detects that the cross key unit 32 is in the state of being pulled out from the main unit 30 by the notification from the sensor 20c (step B1, Yes), and further detects the sensor 20a. , 20b, when it is detected that the display unit 31 is in a closed state where the display unit 31 is overlaid with the main unit 30 so as to expose the display 36 (step B2, Yes), the usage pattern shown in FIG. It is determined that it has been changed to.

  In this case, the switching control unit 10e causes the display unit 11 to change the display direction of the image on the display 36 (step B3). That is, the image displayed in the usage pattern 1 shown in FIG. 3A is rotated 90 degrees to the left and displayed. Thereby, when the user holds and operates the mobile phone 1 according to the usage mode 2, the image displayed on the display 36 can be oriented correctly.

  In the example shown in FIG. 6, the cross key 37 is arranged on the left side of the display 36. However, for example, the cross key 37 is arranged on the right side and the other function keys 35 are arranged on the left side. Also good. In this case, the function switching table 10f is set with a function corresponding to each key arrangement, and the switching control unit 10e assigns the function according to the usage pattern. Further, the switching control unit 10e causes the image displayed in the usage pattern 1 to be rotated 90 ° to the right and displayed.

  Further, whether the usage mode shown in FIG. 6 is used or whether the cross key 37 and the function key 35 are arranged in the opposite direction may be determined by the game content of the game program 17a. In this case, the switching control unit 10e may execute function switching control and display switching control in response to an instruction from the application unit 10d (game program 17a).

  Further, by mounting a sensor for detecting the posture (tilt) on the mobile phone 1, either the usage mode shown in FIG. 6 or the usage mode in which the cross key 37 and the function key 35 are arranged in the left and right directions is used. May be detected, and function switching control and display switching control may be executed in response to this detection.

  Thus, in the mobile phone 1 according to the present embodiment, when the game is to be executed, not only the usage mode suitable for the game in which the key is operated with one hand as shown in FIG. As shown in the figure, it is possible to make a use form suitable for a key operation with both hands. That is, without using an additional device such as a controller separate from the mobile phone 1, it is possible to use the same form of use as a portable game machine in which keys are arranged on both sides of the display 36. For this reason, it is possible to use a game program that requires key operations with both hands, such as is executed on a portable game machine.

  In addition, since the function switching control and the display switching control are executed by detecting whether the current mode is the usage mode 1 or 2 according to the notification from the sensor 20, the user performs an operation to change the usage mode. There is no need to perform any special setting operations. In addition, since the user can arbitrarily select which of the usage modes 1 and 2 is used to execute the game, the usage mode can be executed for one game.

  In the above-described configuration, the length of the display unit 31 in the longitudinal direction is shorter than the length of the main unit 30 in the longitudinal direction so that the function key 35 is exposed even when they are overlapped by the hinge mechanism 33. However, the lengths of the display unit 31 and the main unit 30 may be substantially the same. In this case, the function key 35 may be stored in the main unit 30 in the same manner as the cross key unit 32, and may be used by being pulled out when the display unit 31 and the main unit 30 are overlapped. The switching control unit 10e detects through the sensor that the unit provided with the function key 35 has been pulled out, and executes function switching control and display switching control.

  In the above description, the folding-type mobile phone 1 is described as an example, but the slide-type mobile phone 1 can also be targeted.

FIG. 11 is a diagram showing an external configuration of the slide-type mobile phone 1.

  The upper surface of the main unit 52 is provided with a numeric key 57 and a plurality of function keys at one end in the longitudinal direction (the side where the cross key 55 is disposed on the display unit 50). When the function is used, as shown in FIG. 11B, the display unit 50 is slid to expose the numeric key 57 portion provided on the main unit 52. FIG. 12B shows a side view of the state where the display unit 50 is slid and the numeric keys 57 are exposed.

  In addition, a function key unit 53 is attached to the main unit 52 so that the main unit 52 can be taken in and out at the other end where the numeric key 57 is not provided. A plurality of function keys 58 are provided on the upper surface of the function key unit 53. The function key unit 53 is housed in the main unit 52, for example, with a structure as shown in FIG. 5, and can be pulled out by a user operation as shown in FIG. 11C. FIG. 12C shows a side view of the state in which the function key unit 53 is pulled out from the main unit 52.

  As shown in FIG. 11 (c), by pulling out the function key unit 53, it is possible to obtain a use form suitable for a key operation with both hands.

  11 and FIG. 12 also omits detailed description on the assumption that the function switching control and the display switching control are performed in the same manner as the folding cellular phone 1 described above. . 11 and 12, a sensor for detecting that the function key unit 53 is pulled out from the main unit 52 is provided in addition to a sensor for detecting that the display unit 50 is slid. The switching control unit 10e can determine which usage mode the mobile phone 1 is based on the notification from each sensor.

  In this way, the slide-type mobile phone 1 is not only suitable for use in games in which keys are operated with one hand, but is also suitable for use with keys operated with both hands as shown in FIG. Can be.

  Note that the present invention can also be applied to a mobile phone having a structure other than a folding type or a slide type, for example, a bar type mobile phone that does not include a movable unit. In this case, a configuration in which a functional unit provided with a function key used in a game is stored at one end of the main body of the mobile phone and can be pulled out by a user operation. This allows the display to be placed in the center with the existing keys provided on one end of the mobile phone body adjacent to the display and the function keys provided on the functional unit provided on the other side. It is possible to use and operate keys.

  Further, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
